The solubility of 4-(3,4-dichlorophenyl)-1-tetralone in the mixture of ethanol and acetone was measured by using a laser technique in the temperature range from 283.15 to 323.15 K. The results were correlated with a semiempirical equation. The experimental solubility and correlation equation in this work can be used as essential data and models in the purification process of 4-(3,4-dichlorophenyl)-1-tetralone.
